Answer 1

Answer:

Ist find the area of trapezium ACDE:

area of trapezium = sum of parallel sides× h/2

ar(ACDE)= (12+8)×2/2=20cm^2

now finding the area of Triangle ABC:

area of triangle = 1/2×B×H

ar(ABC)=1/2×4×12=24cm^2

total area= ar(ACDE)+ar(ABC)

= 20cm^2+ 24cm^2=44cm^2

44cm^2 is the answer.
